Modern fiberglass textile production has the basic characteristics of high-speed, high efficiency, high-quality, large package.Process route fully in line with product quality requirements.
Taking the textile production process of electrical insulation cloth as an example,The basic process route is: twist strand →Withdrawal→Warping→Clearstarch yarn→Wear comprehensive→Jet weaving→Inspection→Pre-desizing→Thermal desizing→Surface coating treatment→Test→Finished product packaging
It is the raw material of high-quality raw silk production ,it takes the characteristics of special textile equipment for the production .Which is made of the process of drawing a large package of raw silk cylinder placed in the forced unwinding of the active feeding of the yarn on the retractor machine,The yarn is twisted into yarn feeding tube by guide yarn hook and ring,The need for pultrusion and twist of the product, will be a fixed length of the bottle-type tube inserted in the twisting machine of the first twist twisting spindle by the yarn guide, feed roller, yarn guide hook to twist the twisting spindle, Ingot twisted into a bottle-type tube yarn.The yarn tube is placed on the creel of the warper, the yarn is drawn to the whole warper by the single yarn tensioner, the yarn guide and the tension roller, and the yarn is wound at constant linear speed and constant tension by the warping machine. A fixed length of the warp beam.Batch warping process is adopted.The number of warp yarns is 1/4 ~ 1/5 of the total number of the fabric.And then a number of warping axis placed in the pulp axis frame, together traction to the slurry tank, the use of double-dip single-pressure way to sizing the warp with a slurry soaked, the warp through the hot air drying to a certain extent, in the cylinder Completely dried, in the sizing of the winding head into a certain length, single yarn pulp slurry coated axis.Slurry commonly used starch slurry and chemical PV A slurry two categories. In the wear process will healds, menopausal tablets put on, made of woven shaft.Weaving the use of jet weaving, glass fiber for the nozzle, the warp by serous protection for high-speed weaving.Weaving the use of sub-high-style large package coiling method. Post-processing using sub-processing, so that the final product quality to achieve “net, uniform, Qi” requirements.The pre-desizing machine passes the tested fabric roll through the high-temperature hot-air zone, treating the sizing agent on the yarn, the sizing agent, and the sizing agent on the weft yarn to a very low level, Dispose of cloth roll.A high-quality cloth for electric insulation containing a silane-treating agent was produced in a surface treatment coated by water washing (drying → drying) → dipping → drying (trimming) → winding.due to the use of sizing process ,the products can make good performance of yarn twist low, fabric surface smoothness, impregnation with resin .
Traditional fiberglass textile technology is produced by crucible drawing raw silk as raw materials, Using cotton spinning equipment modification, and then production.Using the following technical line: winding → raw silk withdrawal and twist → warping → wear comprehensive → weaving → inspection → post-processing → inspection → packaging.
Bending machines, and twisting machines are using roller traction, yarn free rewinding.After the friction point of yarn, the yarn become damage.The yarn is twisted through the wire guide hook ring, the diameter of the ring is small, the maximum package volume of the tube is 0. 8 kg / tube yarn, and the machine control is simple.The use of sub-warping, warp tension uniformity difficult to control.The use of sub-warping, warp tension uniformity difficult to control. The creel uses the old gravity disc type tensioner, it is not suitable for the glass fiber characteristic, the tension is difficult to control.Warping length is less than 1000 meters / warp beam. The loom is a shuttle loom.Warp is not serous protection, shuttle reciprocating movement in the shed and the upper and lower openings, the warp easily damaged, weaving quality is difficult to guarantee.If the use of separate winding weaving, the roll length is up to 1000 meters.Post-processor control, the structure is relatively simple. The use of continuous processing, can not handle high-quality requirements of the glass fiber textile products. Generally, the length of the cloth after the treatment is the same as the length of the fabric.
The traditional textile processing technology because the warp is not sizing, it can not get very good protection. Therefore, only high-twist, low speed, small package for production. The production efficiency is low, the fabric surface is flat and poor, and the resin is poor.
